Organotellurium chemistry
Organotellurium chemistry describes the synthesis and properties of organotellurium compounds, chemical compounds containing a carbon-tellurium chemical bond. Organotellurium chemistry is a lightly studied area, in part because of it having few applications.
The tellurium analogues of common organosulfur and organoselenium functional groups are known. Tellurols are however unstable with respect to oxidation to the ditellurides. Commonly encountered organotellurium compounds are diorganomono- and ditellurides, R2Te and (RTe)2, respectively. Two other families of organotellurium(IV) compounds are well developed: R4−xTeClx and the telluroxides (R2TeO).
Reduced organotellurium compounds are commonly obtained from NaHTe and lithium telluride:
A direct route to organolithium compounds starts from reactions of organolithium or Grignard reagents and Te:
Butyl lithium gives the telluride similarly:
Organotelluride anions can be oxidized or alkylated:
Diorganoditellurides are valued intermediates, especially the aryl derivatives such as diphenyl ditelluride:
One departure from sulfur and selenium chemistry is the availability of the tetrachloride, TeCl4. It reacts with arenes to give aryltellurium trichlorides:
